Zinc Anode 620 Datasheet – Trusted & Legit

Here's a summary of the typical values found in the datasheet:

These manufacturers often provide similar product datasheets and specifications, but may have slightly different offerings or variations.

is a two-component, high-performance, epoxy zinc-rich primer . It is designed for the protection of steel structures in highly corrosive environments, such as marine, offshore platforms, petrochemical plants, and pipelines . Key Technical Specifications

While highly effective in , zinc anodes have limitations: zinc anode 620 datasheet

The 620 profile is optimized for medium-to-heavy structural protection where a low-profile design is required to minimize hydrodynamic drag.

To perform effectively, a zinc anode must meet strict metallurgical standards. Contituent impurities like iron can cause the anode to form a passive crust, rendering it useless. Most 620 datasheets adhere to or ASTM B418 Type I specifications for open seawater application. Weight Percentage (%) Purpose / Effect Zinc (Zn) Remainder (Approx. 99.5%) Primary sacrificial metal Aluminum (Al) 0.10% – 0.50% Promotes uniform dissolution Cadmium (Cd) 0.025% – 0.07% Prevents passive film formation Iron (Fe) 0.005% max Harmful impurity; strictly limited Lead (Pb) 0.006% max Impurity limit Copper (Cu) 0.005% max Impurity limit 4. Electrochemical Performance Characteristics

Approximately 10.6 kg per Ampere-year (23.4 lbs/A-yr). Here's a summary of the typical values found

💡 : A simple chart ranking metals by their "nobility" can help you select the right anode material for your vessel.

The Zinc Anode 620 is a that protects more noble metals (e.g., steel, aluminum) from galvanic corrosion. Because zinc has a more negative electrode potential (−1.05 to −1.10 V) than steel (−0.85 V), it acts as the anode in an electrochemical cell when connected and submerged in an electrolyte.

Typical alloying controls include:

: Like most epoxy products, it may chalk or discolor when exposed to direct sunlight. www.bergerarabiapc.com comparison between Zincanode 620 and other zinc-rich primers like the zincanode 620 - Berger Protective Coating [UAE]

recommends installing plates on the bottom of the hull, specifically between the transom and the rear third of the vessel. Are you planning a haul-out or scheduled maintenance?
